All sellers making retail sales of taxable goods or services in Nebraska are required to register with the state and collect and remit sales tax. As Nebraska is a Streamlined Sales Tax state, out-of-state businesses without a sales tax obligation are encouraged to register for sales tax purposes.
Since the kinetic energy increases with the square of the speed, an object doubling its speed has four times as much kinetic energy. For example, a car traveling twice as fast as another requires four times as much distance to stop, assuming a constant braking force.
Kinetic Energy. Kinetic energy is energy of motion. Objects that are moving, such as a roller coaster, have kinetic energy (KE). If a car crashes into a wall at 5 mph, it shouldn't do much damage to the car.But if it hits the wall at 40 mph, the car will most likely be totaled.Kinetic energy is similar to potential energy.inetic energy is energy of motion. Objects that are moving, such as a roller coaster, have kinetic energy (KE). If a car crashes into a wall at 5 mph, it shouldn't do much damage to the car.
